Q:Can I use steel bar instead of steel bar?
But there is a difference between steel reinforcement ratio can good toughness steel reinforced high strength reinforced surface than the thread in the engineering application of the surface force can he assisted according to what you want instead of general effect is no problem except in mechanical parts to replace.
Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
Method of calculating reinforcement weight, unit length, weightD*d*0.00617= (6 in 7)For example, 8mm steel 8*8*0.00617=0.39488 take 0.395Round steel and rib are calculated the same wayRound bar 8 is rolled up, usually between 2~4 tonsYou'll have to straighten it up, straighten it up, and straighten it up
Q:Could you tell me what is the difference between steel pipe and round steel?
The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of steel, widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
See more big steel bar, there is theoretical weight. After all, rebar is threaded, and round steel is also used.
Q:How many tons of pressure can the round steel of 70 inches bear?
As the diameter of about 11.5 cm diameter 180 cm long in the middle of the force which kind of force will be smaller if the curvature is hollow capability hollow wall thickness to achieve much greater strength than solid to do not understand what the best please say a little more thank you good answer is a plus
Q:What's the difference between bearing steel and round steel?
Steel: steel widely used, a wide range of products, according to the shape of the cross section, the steel is generally divided into profiles, plates, pipes and metal products in four categories. Steel is a material of shape, size, and performance made by pressure processing of ingots, billets, or steel. Most steel processing is through the pressure processing, so that the processed steel (billets, ingots, etc.) plastic deformation. According to the steel processing temperature, can be divided into cold processing and hot processing two.
Q:How about tempering No. 45 round bar?
During quenching and tempering, the whole section of the workpiece is quenched and the microstructure of the workpiece is obtained with fine acicular quenched martensite. By tempering at high temperature, the microstructure with uniform tempered bainite is obtained. It is impossible for a small factory to do metallographic analysis of each furnace. It is generally used only for hardness testing. That is to say, the hardness of the quenched material must be reached by the quenching hardness of the material, and the hardness after tempering shall be checked according to the requirements of the drawing.
Q:What is the tensile strength of Q235 round steel?
Nominal diameter 8-20 mm, yield point is greater than or equal to 235MPa, tensile strength greater than or equal to 370MPa, elongation is greater than or equal to 25%.
Q:How about the difference between round steel and shaped steel? Where are they mainly used?
Section steel is a general term, round steel is a kind of section steel, mainly used in building structure, mostly for engineering steel.
Q:Is there any technique for welding round steel?
Weldment pair:Welding round steel, joining two end, processing 30 degrees slope, center left 3--4mm welding root, two pieces of welding set time, the center stay 4--5mm gap, spot welding positioning.
